Just to take up what Firefly Bob is saying
He is far too nice to say what he is thinking.
Is your school the type that introuduces you to the complete circuit exercise in the first hour, RT as well, if so no wonder it is tiring.
Also notice FBs leaning towards Go Arounds rather than Landings at this stage. Its not a great landing you should be aiming for but the ability to make a great go around.
